What is Sigmoidoscopy? Does it Hurt?

Sigmoidoscopy is considered to be a reliable and safe diagnostic method. It allows the doctor to obtain a large amount of information about the state of the sigmoid and rectum, as well as the anus. The practice is conducted using a flexible probe with an illuminator and a video camera at the end.

The colon has a length of about one and a half meters and consists of several sections - the cecum with the vermiform process, the colon and sigmoid colon. The sigmoid colon (colon sigmoideum) has two bends that give this part of the intestine a resemblance to the Greek letter "sigma" ("ς"). The sigmoid colon passes into the rectum (rectum), which in turn ends with the anus or anus.

Sigmoidoscopy is used in cases where there is a suspicion of a lesion in the terminal part of the large intestine, i.e. sigmoid and rectum, as well as the anus. Most often, it is used to determine the cause and exact localization of bleeding, ulcers, fistulas, polyps, diverticula, determine the causes of abdominal pain, constipation or diarrhea, inflammation of the mucous membrane, detection of foreign bodies.

This practice is also very informative if there are suspected neoplasms in the terminal parts of the gastrointestinal tract. In the process of examining the intestinal walls, a biopsy (sampling) of tissues for the histological examination can be performed. In addition, during the diagnosis, it is possible to perform therapeutic practice, for example, coagulation of tissues, removal of small neoplasms, the introduction of drugs into the intestinal lumen. It is worth saying that endosurgical treatment methods are now used quite often due to their low invasiveness and wide capabilities.

In some cases, general anesthesia is used. Sigmoidoscopy is painless due to prior local anesthesia of the examined area. The depth of insertion of the probe is usually limited to 30-35 cm, but if necessary, with the help of a sigmoidoscope it is possible to investigate more distant parts of the intestine, up to the left (splenic) angle of the colon. To improve imaging conditions, a small amount of gas is injected into the intestinal lumen, which stretches the intestinal walls and makes natural intestinal folds available for inspection.

Due to the high reliability of this practice and the absence of contraindications, sigmoidoscopy is included in the list of mandatory preventive procedures that allow timely detection of various tumors and polyps in the rectum and sigmoid colon. However, the procedure should always use well-maintained sigmoidoscopes

Does sigmoidoscopy hurt?

Sigmoidoscopy is actually painful, according to reviews and comments from the patient after the procedure. It is worth noting that during tool insertion in the rectum, the patient will experience discomfort. That is why, to facilitate the progress of the practice, many experts prefer immersing the patient in a state of drug sleep.

This method of the examination allows you to achieve the effect of delicate anesthesia without significant inhibition of all systems of the human body. Medication sleep caused by sedation will last no more than 30-40 minutes. This time will be more than enough to complete a completely painless examination of the patient's rectum.
